The Long Perng 1.25" Twist Lock star diagonal features a twist-tight clamping mechanism that securely holds 1.25" eyepieces and accessories with a simple clockwise twist of its red aluminum collar. Unlike diagonals with thumb screws, the Long Perng Twist Lock diagonal applies equal inward pressure to center eyepieces and camera nosepieces in the optical path of the telescope. There is no marring, scratching, or gouging of the eyepiece barrel or nosepiece, and there's no thumbscrew to accidentally fall out in the dark. The knurled aluminum twist-tight collar is easy to grip and adjust even while wearing gloves.
The Long Perng 1.25" Twist Lock star diagonal uses a mirror with dielectric coatings of >99% reflectivity to provide the brightest possible views possible through a refractor or Cassegrain telescope. Note that it cannot be used with Newtonian/Dobsonian reflectors.
This diagonal incorporates a rugged anodized aluminum housing with internal baffles to eliminate internal reflections and ensure optimal contrast. It also offers a long working life without degradation since dielectric coatings are more durable than less expensive enhanced aluminum coatings.
The diagonal includes two end caps, and the 1.25" nosepiece is threaded to accept standard 1.25" astronomy filters with M28.5x6 threads.
